To aZZ whom it may concern: link q, having pivotal connection both with Be it known that we, CHARLES E. lVlllLLER, the block and with the lugs on the bracket m. residing in Paterson, and JAMES E. JACKSON, 0* designates the shipper-lever of the loom,

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a stop-motion mechanism for narrowware looms, the combination, with the batten, of a reciprocating part on the batten movable transversely of the movement thereof, an elastic flexible member adapted to actuate the power-controlling mechanism of the loom, a detent normally holding said member retracted, and means, movable with said reciprocating part, for actuating said detent to release said member, substantially as described.

2. In a stop-motion mechanism for narrowware looms, the combination, with the batten, of a reciprocating part on the batten movable transversely of the movement thereof, an elastic flexible member adapted to actuate the power-controlling mechanism of the loom, a hook normally holding said member retracted, and'engageable blocks, one of said blocks being movable with said reciprocating part and the other being connected to said hook, subhook normally holding said member retracted, and engageable blocks, one of said blocks being movable with said reciprocating part and the other being connected to said hook, the face of one block which is adjacent the other having step-like projections, substantially as described.

4:. In a stop-motion mechanism for narrowware looms, the combination, with the batten, of a reciprocating part on the batten movable transversely of the movement thereof, an elastic member adapted to actuate the power-controlling mechanism of the loom, a detent normally holding said member retracted, and means, movable with said reciprocating part, foractuating said detent to release said member, substantially as described.

5. In a stop-motion mechanism for narrow- Ware looms, the combination of two parts adapted to impinge the one against the other to effect the stopping, one of said parts being adapted to move in a curved line and one of said parts, also, having the face thereof adjacent the other part provided with steps arranged in a curved line, substantially as described.

In'testimony that We claim the foregoing We have hereuntoset our hands this 24th day of December, 1901.
